Habilidades sociais e características pessoais em escolares de Belém

Este estudo relacionou a frequência da emissão de reação socialmente habilidosa, não-habilidosa passiva e não-habilidosa ativa às variáveis da criança (sexo, idade, condições clínicas). Participaram 57 meninos e 52 meninas, entre seis e 12 anos. O Questionário de Caracterização da Criança (QCC) levantou informações sobre sexo, idade e condições clínicas e o Inventário Multimídia de Habilidades Sociais de Crianças (IMHSC-Del Prette) avaliou as habilidades sociais, respondidos pelos cuidadores e escolares, respectivamente. Utilizou-se os testes U de Mann-Whitney, o coeficiente de correlação de Pearson e o teste t para análises dos dados. Os resultados indicaram: (a) diferenças significativas na adequação das reações habilidosas e não-habilidosas (p < 0,001); (b) aumento do repertório de habilidades sociais conforme o avançar dos anos (p < 0,001); e (c) meninas apresentaram mais frequência de habilidades sociais que meninos (p = 0,040). Não houve associações significativas entre habilidades sociais e condições clínicas (p = 0,539). Verificou-se que sexo e idade podem interferir na presença e desempenho de repertório socialmente habilidoso. Sugerem-se outras técnicas de avaliação que complementem os dados investigados e possibilitem intervenções futuras para amostras semelhantes.

Comportamentos de crianças do espectro do autismo com seus pares no contexto de educação musical

O Transtorno do espectro do autismo (TEA) é marcado por prejuízos nas áreas de interação social, comunicação, comportamento e processamento sensorial. Aspectos relacionados a prejuízos no repertório de interação social, bem como estratégias para torná-la mais adequada têm sido amplamente estudados. Dentre estas estratégias, as que utilizam música têm recebido atenção. O presente estudo tem como objetivo investigar os benefícios da educação musical ao desenvolvimento da interação social de crianças com seus pares, focando-se na qualidade e na frequência da apresentação de tais comportamentos. Participaram duas crianças com TEA, com idades de cinco e seis anos, em aulas de percussão em grupo. Os instrumentos utilizados foram a Ficha de dados sociodemográficos e de desenvolvimento, para traçar os perfis dos participantes; e o Protocolo de observação de comportamentos de crianças com TEA com seus pares, para a análise comportamental, durante oito aulas/percussão (240 minutos). Os resultados sugerem que ambos apresentaram tendência ao aumento de iniciativas e respostas espontâneas e à diminuição de comportamentos não funcionais. Verificou-se a ocorrência do uso de estereotipias para tentativas de/e interações, embora esporadicamente. Destacaram-se os papéis do contexto, dos perfis das crianças, e do manejo comportamental por adultos, na promoção de interações.

Using Three Dimensional Motion Capture Technology to Describe and Assess Piano Technique: A Case Study

The purpose of the study was to examine any differences that exist in the quality of motions employed by pianists when they are sight-reading versus performing repertoire. A secondary question of interest was whether or not an improvement in the efficiency of motion could be observed between two sight-reading trials of the same musical excerpt. While data analysis for the full study is ongoing, the following results from a case study are illustrative.

SOCIAL MONOGAMY AND BIPARENTAL CARE OF THE NEOTROPICAL SOUTHERN BAMBOO RAT (KANNABATEOMYS AMBLYONYX)

We analyzed social patterns indicative of the mating system and parental care in a population of the southern bamboo rat (Kannabateomys amblyonyx). This arboreal rodent feeds exclusively on bamboo stems and leaves. We conducted fieldwork from August 2003 to October 2004 in southern Brazil (30 degrees 20`-30 degrees 27`S, 50 degrees 50`-51 degrees 05`W), in patches of introduced Chinese bamboo (Bambusa tuldoides). We captured 18 individuals, 7 of which were adults that received radiotransmitters and were followed from 1 to 12 months. Another 5 animals (adults or subadults) received colored collars. We observed paternal care, delayed juvenile dispersal, and reduced degree of sexual dimorphism, all of which are traits typical of social monogamy. Mated males showed a direct parental behavioral repertoire similar to that of females (with the obvious exception of nursing), including grooming, huddling, and food provisioning. Potential monogamy in this species seems to be a flexible strategy linked to low density of bamboo patches. Females were confined to widely spaced., small home ranges, decreasing the possibility of male defense of and access to > 1 female. The arboreal habits of the species possibly increase the risk of inexperienced young falling from trees or else being depreciated when moving exposed through branches. This risk is probably reduced by the extensive biparental care observed, including the providing of low-energy plant food to young in the nest.

DivIVA-Mediated Polar Localization of ComN, a Posttranscriptional Regulator of Bacillus subtilis

ComN (YrzD) is a small, 98-amino-acid protein recently shown to be involved in the posttranscriptional control of the late competence comE operon in Bacillus subtilis. We show here that ComN localizes to the division site and cell poles in a DivIVA-dependent fashion. Yeast two-hybrid and glutathione S-transferase pulldown experiments showed that ComN interacts directly with DivIVA. ComN is not essential for the polar assembly of the core competence DNA uptake machinery. Nevertheless, polar localization of ComN should play some role in competence acquisition because delocalization of ComN leads to a small reduction in competence efficiency. We found that ComN promotes the accumulation of its target comE mRNA to septal and polar sites. Thus, we speculate that localized translation of ComE proteins may be required for efficient competence development. Our results underscore the versatility of DivIVA as a promoter of the differentiation of bacterial poles and demonstrate that the repertoire of polarly localized molecules in B. subtilis is broad, including a regulator of gene expression and its target mRNA. Moreover, our findings suggest that mRNA localization may play a role in the subcellular organization of bacteria.

Mating behaviour, nympho-imaginal development and description of a new Mesabolivar species (Araneae: Pholcidae) from the Brazilian dry forest

A new species of Mesabolivar is described from Brazilian forests: Mesabolivar delclaroi. The mating behaviour, postembryonic development, number of egg sacs and eggs, birth rate, number of instars, developmental time until adulthood, sex ratio and size of cephalothorax (per instar) were recorded. The sexual behaviour was described and categorized into four steps: courtship, pre-copulation, copulation and post-copulation. After hatching, individuals presented five instars until maturity. The mean number of eggs (42 +/- 16.6) and live births (31.5 +/- 3.4) of the first egg sac were significantly greater than that of a second one (23.8 +/- 3.8, and 19.25 +/- 3.9, respectively). The developmental time from birth to adulthood (130.8 +/- 9.6 days) did not differ significantly between egg sacs produced (128.61 +/- 11.1). The size of the cephalothorax did not differ among adults or between sexes. The sex ratio revealed a shift in favour of females (4: 3).

Using the Social Skills Inventory in the Diagnosis of Social Anxiety Disorder

This study aimed to assess the relationship between clinical and behavioral manifestations of the Social Anxiety Disorder (SAD) and verify the discriminative validity of the Social Skills Inventory (SSI-Del-Prette) in the diagnosis of this disorder. The participants were 1,006 undergraduates, aged between 17 and 35 years old, both genders. Subsequently, 86 participants were randomly selected from the initial sample and grouped as SAD cases and non-SAD cases through systematic clinical evaluation. The results indicated that the more elaborate the repertoire of social skills of an individual is, the lower his/her likelihood of meeting the screening criteria of diagnostic indicators for SAD. Furthermore, the SSI-Del-Prette has demonstrated to significantly distinguish individuals with and without SAD, evidencing, thus, its discriminative validity.

Preserving the B-Cell Compartment Favors Operational Tolerance in Human Renal Transplantation

Transplanted individuals in operational tolerance (OT) maintain long-term stable graft function after completely stopping immunosuppression. Understanding the mechanisms involved in OT can provide valuable information about pathways to human transplantation tolerance. Here we report that operationally tolerant individuals display quantitative and functional preservation of the B-c ell compartment in renal transplantation. OT exhibited normal numbers of circulating total B cells, naive, memory and regulatory B cells (Bregs) as well as preserved B-cell receptor repertoire, similar to healthy individuals. In addition, OT also displayed conserved capacity to activate the cluster of differentiation 40 (CD40)/signal transducer and activator of transcription 3 (STAT3) signaling pathway in Bregs, in contrast, with chronic rejection. Rather than expansion or higher activation, we show that the preservation of the B-cell compartment favors OT. Online address: http://www.molmed.org doi: 10.2119/molmed.2011.00281

Combined snake venomics and venom gland transcriptomic analysis of Bothropoides pauloensis

Unraveling the repertoire of venom toxins of Bothropoides pauloensis was assessed by snake venomics and venom gland transcriptomic surveys. Both approaches yielded converging overall figures, pointing to metalloproteinases (similar to 37%), PLA(2)s (26-32%), and vasoactive (bradykinin-potentiating) peptides (12-17%) as the major toxin classes. The high occurrence of SVMPs, PLA(2) molecules, vasoactive peptides, along with serine proteinases, explains the local and systemic effects observed in envenomations by B. pauloensis. Minor (<3%) C-type lectin, serine proteinase, L-amino acid oxidase, nerve growth factor, and CRISP molecules were also identified in the transcriptome and the proteome. Low abundance (0.3%) EST singletons coding for vascular endothelial growth factor (svVEGF), ohanin, hyaluronidase, and 5' nucleotidase were found only in the venom gland cDNA library. At the molecular level, the transcriptomic and proteomic datasets display low compositional concordance. In particular, although there is good agreement between transcriptome and proteome in the identity of BPPs, PLA(2) molecules and L-amino acid oxidase, both datasets strongly depart in their C-type lectin and SVMP complements. These data support the view that venom composition is influenced by transcriptional and translational mechanisms and emphasize the value of combining proteomic and transcriptomic approaches to acquire a more complete understanding of the toxinological profile and natural history of the snake venom.
